[0002] With an aging population and increasing demands from people with disabilities, electric wheelchairs, as an important assistive mobility tool, are receiving significant attention for their functionality, safety, and convenience. The frame, as the core supporting structure of an electric wheelchair, directly impacts the user experience.

[0003] Currently, common electric wheelchair frames on the market have certain deficiencies in folding functionality and safety performance. Regarding the folding structure, most existing electric wheelchair frames use traditional methods, such as simple hinges or single linkages. These structures often lack stability when unfolded, easily becoming shaky or loose after prolonged use, affecting user safety. Furthermore, such folding structures require multiple cumbersome steps during operation, making quick folding difficult, especially for users with mobility impairments. In terms of safety, existing electric wheelchair frames typically lack effective visibility enhancement devices. While some electric wheelchairs may have simple lighting devices, these are often poorly positioned and unevenly distributed, failing to provide an effective indication range along the front and back of the wheelchair. At night or in low-light environments, other road users may have difficulty noticing the electric wheelchair's presence and direction of travel, easily leading to traffic accidents and seriously affecting the safety of electric wheelchair users.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0020] like Figures 1 to 2 As shown in the figure, a specific embodiment of this utility model provides a multi-functional frame for an electric wheelchair. This frame structure has the advantages of convenient folding and unfolding and rich functionality. Specifically, it includes horizontally spaced frame frames 100, with folding components between the frame frames 100. A backrest frame 110 is provided at the upper end of the frame frame 100 corresponding to the rear side of the wheelchair. A light strip module 120 is provided on the outer side of the upper end of the frame frame 100 along the front and rear of the wheelchair. A backrest platform 130 is provided on the inner side of the upper end of the frame frame 100 with front and rear spaced apart. The folding components include a pair of inverted U-shaped folding frames 200. The two sides of the folding frames 200 cross each other in an X shape and rotate with each other at the cross position. The lower ends of the folding frames 200 are hinged to the lower ends of the corresponding frame frames 100. After the frame frames 100 are horizontally unfolded, the upper ends of the two folding frames 200 abut against the backrest platforms 130 at the upper ends of the two frame frames 100.

[0021] like Figures 1 to 2As shown, this embodiment includes a folding assembly between the two vehicle frames 100, forming a foldable frame structure. The folding assembly allows the vehicle frames 100 to unfold when they are far apart and fold when they are close together. A light strip module 120 is arranged along the front and back of the wheelchair on the upper outer side of the vehicle frame 100, providing visibility and serving as an indicator to improve wheelchair safety. The light strip module 120 can be an LED light strip structure, controlled by a corresponding circuit controller. The two folding frames 200 adopt… The cross arrangement forms a scissor folding structure. When the two folding frames 200 are unfolded outward, their upper ends can be locked into the abutment platform 130, resulting in high unfolding stability. During the folding process, the two vehicle frames 100 move closer to each other simultaneously to achieve rapid folding, which is convenient for operation. In practical applications, the upper end of the folding frame 200 can be equipped with spaced mounting holes for connecting the flexible seat cushion of the wheelchair. In addition, the backrest frames 110 are used to install the backrest structure, and the upper end of the backrest frames 110 is also hinged with an armrest frame for easy pushing of the wheelchair.

[0022] like Figures 1 to 2 As shown, in order to improve the stability of the folding frame 200, a connecting frame 300 is hinged to the abutment platform 130 in this embodiment. The other end of the connecting frame 300 is hinged to the corresponding side of the folding frame 200. In this way, when the folding frame 200 is unfolded or folded, the connecting frame 300 can rotate synchronously. Especially after the vehicle frame 100 is folded, the connecting frame 300 prevents the upper end of the folding frame 200 from detaching from the vehicle frame 100.

[0023] As mentioned earlier, after the vehicle frame 100 is unfolded, the upper end of the folding frame 200 needs to be inserted into the abutment platform 130. In order to ensure the overall stability after unfolding, this embodiment provides a positioning groove at the upper end of the abutment platform 130 for the upper end of the folding frame 200 to be inserted. In this way, the upper end of the folding frame 200 can be completely inserted into the positioning groove, which can prevent the folding frame 200 from shaking, thereby ensuring the overall structural stability.

[0024] As mentioned above, the lower two sides of the inverted U-shaped folding frame 200 need to be hinged to the vehicle frame 100. In this embodiment, hinge parts 140 are provided on the front and rear sides of the lower end of the vehicle frame 100 for hinged to the lower two sides of the folding frame 200.

[0025] like Figures 1 to 2 As shown, in this embodiment, a leg support frame 150 for mounting a folding leg rest is also hinged to the front side of the lower end of the vehicle frame 100. In this way, the leg support frame 150 can be rotatably mounted on the front end of the vehicle frame 100, enriching the wheelchair's functionality.

[0026] Since a light strip module 120 is installed on the outer side of the upper end of the vehicle frame 100, this embodiment provides a light strip groove arranged along its front and rear along the outer side of the upper end of the vehicle frame 100. The light strip module 120 is embedded in the light strip groove, which provides protection and prevents the light strip module 120 from protruding from the vehicle frame 100 and being damaged by wear. In addition, to improve safety, this embodiment also provides an anti-rollover frame 160 arranged outwardly at the rear side of the lower end of the vehicle frame 100 for installing anti-rollover wheels, which can prevent the wheelchair from tilting backward during travel.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
